CHALLENGE: According to Newton's first law, shouldn't the Moon fly off in a straight line into interstellar space? Why does it orbit the Earth?
The moon is acted on constantly by a force vector (gravity) that tries to pull it down to Earth. This force is exactly counterbalanced by the inertia of the Moon, which tries to fly away in a straight line. The speed of the Moon around the Earth is nearly constant, but its velocity is always changing because of the force imposed by the gravitational attraction between the Moon and the Earth.**
predicts the behavior of objects for which all existing forces are balanced. The first law - sometimes referred to as the law of inertia - states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Objects at equilibrium (the condition in which all forces balance) will not accelerate.
Pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
The third law says that for every action (force) there is an equal and opposite reaction (force). Forces are found in pairs. It's an issue of symmetry. Acting forces encounter other forces in the opposite direction. There's the example of shooting a cannonball. When the cannonball is fired through the air (by the explosion), the cannon is pushed backward. The force pushing the ball out was equal to the force pushing the cannon back, but the effect on the cannon is less noticeable because it has a much larger mass.

Newton's First Law of Motion (Inertia)
predicts the behavior of objects for which all existing forces are balanced. The first law - sometimes referred to as the law of inertia - states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Objects at equilibrium (the condition in which all forces balance) will not accelerate.

Newton's Second Law of Motion (Acceleration)
Pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Newton's Third Law of Motion (Action-Reaction)
The third law says that for every action (force) there is an equal and opposite reaction (force). Forces are found in pairs. It's an issue of symmetry. Acting forces encounter other forces in the opposite direction. There's the example of shooting a cannonball. When the cannonball is fired through the air (by the explosion), the cannon is pushed backward. The force pushing the ball out was equal to the force pushing the cannon back, but the effect on the cannon is less noticeable because it has a much larger mass.
